Common questions

Short answers from the full credit card processing FAQ.

How do I contact Avendo support?: Use the contact page on the main Avendo website at www.avendo.tech/contact-us. Include your business name, website, and a short description of your question. For a payment issue, add example transaction dates and amounts, but never send full card numbers in a message. More in the FAQ
Where do I sign in to my Avendo dashboard?: Existing merchants sign in through the merchant dashboard login on the main Avendo website, at avendo.tech/sign-in-to-avendo-dashboard. The dashboard is where you review routing and processing reports. If you cannot access your account, contact Avendo through its contact page for help. More in the FAQ
What should I do if transactions are being declined?: Declines usually come from the card issuer, for reasons such as insufficient funds, suspected fraud, or mismatched details. First check the decline reason shown in your reports or processor dashboard. If a pattern appears across many customers, contact Avendo support with example transaction times and amounts so the team can investigate. More in the FAQ
Why is my processing statement so hard to read?: Statements often mix interchange, network fees, and processor markups under different names, which makes total cost hard to see. Avendo provides clearer pricing and processing reports for this reason. If you are evaluating a change, bring a recent statement when you contact Avendo so the team can explain how routing would apply. More in the FAQ
How long does Avendo onboarding take?: Avendo describes its onboarding as fast, but the exact timeline depends on your checkout and processor setup, so this site does not publish a fixed timeframe. The quickest way to get an estimate for your business is to contact Avendo with your platform and current processor details ready. More in the FAQ
Does Avendo work with PCI-compliant processors?: Yes. Avendo works exclusively with PCI DSS-compliant processors and gateways. PCI DSS is the card industry’s data security standard, maintained by the PCI Security Standards Council, for organizations that store, process, or transmit cardholder data. Your own PCI responsibilities depend on your checkout setup, so confirm them with your processor. More in the FAQ
